Title: Image intensifier
Inventor: GOSS ALAN JEROME
IPC: H01J31/50
Filed: 1985-09-25
Abstract: An image intensifier includes a channel plate 1 consisting of a slice of silicon in which a very large number of hollow channels 10 extend through its thickness. The silicon slice is formed with its crystalline <110> direction approximately normal to the faces of the slice, and the channels are formed by the use of an etchant, which etches preferentially in this direction. The walls of the channels are coated with secondary electron emissive material which may be deposited from a vapour including lead oxide and silicon monoxide. A pn junction 5 is formed one micron below the top surface 3 of the plate by diffusing a p-type dopant such as boron into the n-type silicon. <IMAGE>

Patent GB-2183079-A (GB)
Title: Coated metallic conductor
Inventor: O'BRIEN JAMES MARTIN
IPC: H01B7/29
Filed: 1986-11-17
Abstract: A conductor comprises a bundle of metallic strands having an adherent electrically insulating refractory coating 2 which extends around the circumference of the bundle but not around individual strands. The coating may be an oxide of Al, Si, Ta or Ti, or a nitride of Al or Ti. Multiple coatings may be applied e.g. by reactive sputtering. An intermediate metallic layer may be provided. By using a sputtering apparatus (Fig. 4) with provision for admission of oxygen or nitrogen, the stoichiometry of the coating may be progressively varied from a metal to a metal compound. The use of an intermediate layer enhances adhesion and suppresses migration of the conductor metal. A cross-linked layer 3 of a polyether-imide may be provided by extrusion. <IMAGE>
Patent GB-2187367-A (GB)
Title: Control system for local area network
Inventor: YANO TAKASHI
IPC: H04L12/44
Filed: 1986-12-31
Abstract: A control system for a local area network (LAN) is disclosed. A single node is capable of handling a plurality of communications at the same time without resorting to substantial extra costs. In addition, the system is expansible from a small scale which includes a single node to a large scale without modifying the protocol. To establish a further path through a node the first signal to arrive on a previously idle input channel is transmitted on free output channels, the input channels corresponding to those output channels are connected to the output corresponding to said previously idle input channel for an acknowledgement to be returned and a path set up in accordance with the channels over which signals arrive. Nodes and stations can distinguish between different signals and relatively delayed versions of the same signal to detect collisions. The detection of a collision depends solely on the distance between nodes and not on the scale of a network, whereby the practicality is enhanced. Because collision information is delivered to a transmit station even when the transmit station is transmitting the first forward information (call packet), the transmit station is capable of retransmitting and, yet, the communication efficiency remains substantially the same as in a case without a collision.

Patent GB-2220434-A (GB)
Title: Draught excluder
Inventor: KEMP BARBARA
IPC: E06B7/23
Filed: 1988-07-09
Abstract: Draughts beneath doors (10) can be excluded by the use of a partly-inflated lay flat tube (20) which extends along the bottom edge (15) of the door and part of the way up the hinged edge (17). With the door closed, air is introduced into the tube through a non-return valve to inflate it into contact with the floor (13). When the door is opened, the tube relaxes towards its flat disposition, driving air into that part of its length which extends up the hinged edge. This relaxation takes the tube out of contact with the floor while the door is pivoting on its hinges (16). The non-return valve is a flap valve and the tube can be inflated using a drinking straw. <IMAGE>
